Simulation of semi-explicit mechanisms of SOA formation from glyoxal in aerosol in a 3-D model [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
New pathways to form secondary organic aerosol (SOA) have been postulated recently. Glyoxal, the smallest dicarbonyl, is one of the proposed precursors.

Imidazopurinones are markers of physiological genomic damage linked to DNA instability and glyoxalase 1-associated tumour multidrug resistance [PDF]

open access: yes, 2010
Glyoxal and methylglyoxal are reactive dicarbonyl metabolites formed and metabolized in physiological systems. Increased exposure to these dicarbonyls is linked to mutagenesis and cytotoxicity and enhanced dicarbonyl metabolism by overexpression of ...

Chamber studies of SOA formation from aromatic hydrocarbons: observation of limited glyoxal uptake [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
This study evaluates the significance of glyoxal acting as an intermediate species leading to secondary organic aerosol (SOA) formation from aromatic hydrocarbon photooxidation under humid conditions. Rapid SOA formation from glyoxal uptake onto aqueous (

Glyoxal in hyperglycaemic ischemic stroke – a cohort study

open access: yesCardiovascular Diabetology, 2023
Background Hyperglycaemia is frequent in acute ischemic stroke and denotes a bad prognosis, even in the absence of pre-existing diabetes. However, in clinical trials treatment of elevated glucose levels with insulin did not improve stroke outcome ...

Glyoxal-based fixation of Drosophila embryos for immunofluorescence staining and RNA in situ hybridization

open access: yesSTAR Protocols, 2023
Summary: The dialdehyde glyoxal is an alternative chemical fixative that cross-links tissues faster than formaldehyde, retains higher antigenicity, and is less hazardous than either formaldehyde or glutaraldehyde. Here we present a glyoxal-based fixation

A Retrieval of Glyoxal from OMI over China: Investigation of the Effects of Tropospheric NO2

open access: yesRemote Sensing, 2019
East China is the ‘hotspot’ of glyoxal (CHOCHO), especially over the Pearl River Delta (PRD) region, where glyoxal is yielded from the oxidation of aromatics.

Chemical insights, explicit chemistry, and yields of secondary organic aerosol from OH radical oxidation of methylglyoxal and glyoxal in the aqueous phase [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
Atmospherically abundant, volatile water-soluble organic compounds formed through gas-phase chemistry (e.g., glyoxal (C2), methylglyoxal (C3), and acetic acid) have great potential to form secondary organic aerosol (SOA) via aqueous chemistry in clouds ...

Highly Enantio‐ and Diastereoselective Synthesis of Tetrahydrofuran Frameworks via Chiral Lewis Acid‐Catalyzed Formal [3+2] Cycloaddition of Allylsilanes

open access: yesAngewandte Chemie, Volume 138, Issue 39, 21 September 2026.
The first catalytic asymmetric formal [3+2] cycloaddition of allylsilanes delivers cis‐2,5‐disubstituted tetrahydrofuran‐3‐ones that serve as versatile intermediates for the synthesis of diverse bioactive scaffolds. ABSTRACT A formal [3+2] cycloaddition via cyclization/1,2‐hydride shift initiated by nucleophilic attack of allylsilanes has been ...

The continental source of glyoxal estimated by the synergistic use of spaceborne measurements and inverse modelling [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
Tropospheric glyoxal and formaldehyde columns retrieved from the SCIAMACHY satellite instrument in 2005 are used with the IMAGESv2 global chemistry-transport model and its adjoint in a two-compound inversion scheme designed to estimate the continental ...
